Title: Video signal processing circuit for a PAL VTR system
IPC: H04N9/79
Filed: 1982-05-13
Abstract: Known magnetic tape systems for recording and reproducing PAL television signals of the type shown in Figure 1 in which during reproduction the luminance and chrominance signals are processed separately and then combined 19 to produce a signal for application to a domestic television receiver, suffer from the disadvantage that the chrominance signal in the final signal applied to the television set, lags the luminance signal by one line. This defect becomes important if tapes are repeatedly played and re-recorded since the lag becomes cumulative. According to the invention the defect is overcome by delaying the luminance component by one line either before recording (as in Figure 3) or during playback. Several methods for accomplishing this are discussed using glass acoustic delays and semi-conductor delays, such as CCD devices. <IMAGE>
Patent GB-2103400-A (GB)
Title: Data processing system
Inventor: REDDAWAY STEWART FIDDIAN
IPC: G06F15/80
Filed: 1982-07-27
Abstract: A data processor consisting of a plurality of modules each containing a sub-array of processing elements (P). Within each module, the connections to at least two of the elements (P) on one edge of the sub-array share a set of external terminals (12) with the connections to the same number of elements (P) on an adjacent edge of the sub- array. For example, if each sub-array contains 4 x 4 elements, the four elements along the northern edge can share the same four external terminals (12) with the four elements along the western edge, thus reducing the number of external terminals (12, 14, 16) required from sixteen to twelve. <IMAGE>

Title: Method of and apparatus for cleaning fabrics
Inventor: MATTHEWS JOHN CLARENCE
IPC: B08B7/02
Filed: 1983-06-13
Abstract: For cleaning an article formed of non-rigid fabric such as a tubular filter (5) low frequency air pulses are directed at the article in the form of a concentrated beam to cause the material to vibrate while the article is rotated to expose different portions to direct impingement. The frequency is varied in the range 10 to 100 Hz while observing the article through window 24, and the frequency is held constant for a period at those values where the article resonates. The frequency may return to resonant values more than once in a cleaning operation. <IMAGE>

Patent GB-2168865-A (GB)
Title: Switching power supplies
Inventor: KUDO SINJI
IPC: H02M3/338
Filed: 1984-12-20
Abstract: A switching power supply intermittently switches current in a primary winding L1 of a transformer T using a bipolar transistor 1. A capacitor C2 is charged by a voltage induced in a feedback winding L3 of the transformer and the base-emitter path of the bipolar transistor is reverse biased by this charge voltage so as to perform high-speed switching. The application of the reverse bias voltage is performed by a transistor Q2 which is turned on when the emitter (grounded through a resistor R) voltage of the bipolar transistor is increased to a predetermined level. The switching period of the bipolar transistor is determined by a timing capacitor CT which is charged to reverse bias the bipolar transistor when the latter is turned on, and is discharged when it is turned off. An auxiliary winding L4 detects flyback energy, and the ON and OFF times of the bipolar transistor are controlled to stabilize the output voltage even if an output terminal is overloaded. Variable impedance 4 of a photocoupler also provides stabilisation in response to variation in the output voltage from the secondary winding L2. <IMAGE>
